Spreadsheet-Based Form Design and Data Input

ABSTRACT

Methods and systems for form design and data input collection are described. The method at a server system includes receiving a form template in which multiple cells are provided in an array, wherein in the form template a plurality of the cells define formula-based values, and a plurality of the cells include metadata specifying a required format of a cell input. The method includes rendering the form template as a form instance including providing displayable input controls for fields of the form instance based on the cell metadata in corresponding cells of the form template; receiving user inputs into fields in the form instance; and evaluating user inputs to update formula-based values for cells.

FIELD OF THE INVENTION

The technology described in this application relates to form design and data input. In particular, it relates to spreadsheet-based form design.

BACKGROUND TO THE INVENTION

Business processes that require collaboration between different people are often supported by the completion and submission of forms. Many organisations have replaced, or are replacing, paper forms with electronic ones and there are many different ways to do so. However, one of the common approaches involves the use of spreadsheets as templates for forms.

In this case, the business process owner either creates, or supervises the creation, of a template spreadsheet document. A user participating in the business process will then make a copy of the template spreadsheet, filling values in to some of the cells that are blank in the template, and will submit the newly completed spreadsheet form, for example, by attaching it to an email.

Spreadsheets employ a declarative dataflow programming paradigm known as cell-oriented programming. This has been widely adopted by users who would not necessarily regard themselves as computer programmers, but who are sometimes carrying out programming activities through spreadsheets. Spreadsheets are now regarded as one of the most ubiquitous End User Programming (EUP) tools.

This paradigm allows the expression of a set of related logical constructs without having to focus on the particular flow of execution that the computer processor will carry out, as the execution engine is tasked with doing this in a manner transparent to the user. The spreadsheet concept also includes a two-dimensional (or even three-dimensional when extended to multiple sheets) visual layout of data and text that is intuitive and effective.

Forms that support business processes often benefit from being encoded in spreadsheets for a number of reasons, including: the layout of spreadsheets in rows and columns, allowing heterogeneous data to utilise a two-dimensional area effectively in a semi-structured fashion; calculations of values dependent on user-inputted data are often useful (for example, aggregate totals or conversion to other units); macros or spreadsheet extensions allow sourcing of relevant data from other computer systems.

A spreadsheet-based system is ‘Do-It-Yourself’ for the large number of end users that are comfortable with spreadsheet technology. Compared to an enterprise solution, this can make it faster, and, at least initially, less costly, to get an electronic system in place because it does not require the same level of specialist technical services to implement.

However, these advantages are sometimes counter-balanced by some disadvantages, particularly when considered from an enterprise perspective. The disadvantages include the lack of an ability to distinguish between user-entered data and the structure of the form (although this can be mitigated by protecting cells, there is no distinct categorization). The data is semi-structured at best. There is also a lack of an ability to deal with different record sets relating to the same form structure, including summarizing and querying across different record sets—since each form is in a separate file. There is also a lack of workflow tools to enable sequence control, allow for conditional logic, or track the status and approval of forms. The proliferation of files, including old or modified versions of template files, can be very difficult to manage.

It is these disadvantages, among others, that have led many organisations to invest in Business Process Management (BPM) software suites. These suites typically provide tools for designing form templates, together with a mechanism for defining dynamic behaviour. This may be in the form of an Application Programming Interface (API), or through the use of a flowchart-based workflow designer, for example, based on the Business Process Model and Notation (BPMN). They also typically store the data from submitted forms in a centralised database. Although these software suites effectively address many of the weaknesses of a spreadsheet-based system, they typically required highly trained technicians or professional computer programmers to implement.

The preceding discussion of the background to the invention is intended only to facilitate an understanding of the present invention. It should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was part of the common general knowledge in the art as at the priority date of the application.

DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWINGS

The described technology provides method and systems for form generation and data input collection in which the form design is based on a spreadsheet format with associated cell based inputs to which formulae may be applied.

A form makes it straightforward to capture information in data input fields of the form from multiple data provider users and to organize and edit the information. Forms may have simple fields in which any form of data may be entered or complex fields which may include “list boxes” that allow a user to select from a specific list of items and “spin buttons” that allow the user to choose a value.

The described technology leverages the widely accepted and understood format of spreadsheet applications to enable form design based on a spreadsheet format to be carried out and a template converted to a distributable form format.

A spreadsheet is an interactive computer application for organization, analysis and storage of data in tabular form. The application operates on data entered in cells of an array, organized in rows and columns. Each cell of the array may contain either numeric or text data, or the results of formulae that automatically calculate and display a value based on the contents of other cells. As well as performing basic arithmetic and mathematical functions, spreadsheets provide built-in functions for common financial and statistical operations. Spreadsheet programs also provide conditional expressions, functions to convert between text and numbers, and functions that operate on strings of text. The cell-oriented spreadsheet formula-based programming language is used as a basis in the described technology for end-user programming within a form design which is then converted to a form format for distribution and data capture.

FIG. 1 illustrates an embodiment of the described system (100) for spreadsheet-based form design and data input collection. A server (110) may be provided with a form engine (120) which provides a repository of form templates (150) which are distributed to form filing client systems (161-163) where they are interpreted as form instances (170). Data input via the form filing client systems (161-163) may be collated and analyzed by the form engine (120). The form engine (120) may store the data input received from the form instances (170) in a database (130).

A designer system (140) may be provided which may be a client system remote from the server (110) or may be integrated with the server (110). The designer system (140) may include a form designer component (141) for design of a form template (150). The form designer component (141) may be a spreadsheet-based application that may be used via a user interface of the designer system (140). The spreadsheet-based application uses the two-dimensional layout principles of a spreadsheet and allows calculated values to be included in the form based on the cell-oriented programming paradigm, in the spreadsheet formula-based language familiar to users. Spreadsheet functionality of cell-oriented spreadsheet formulae may be applied which may be incorporated into a form instance (170) once the form template (150) is interpreted. The form designer component (141) may enable copy-and-paste functionality from a spreadsheet application (for example. Excel® or Google Sheets®).

Additional functionality may be provided by the form designer component (141) for defining further features which are incorporated into the form template (150) and applied when the form template (150) is interpreted as a form instance (170). In particular, the additional functionality may include rich metadata specifying a required format or type of data of a field in the form template. The additional functionality may also include defining validation rules and other supporting logic using the formula-based programming language for the input fields of the form template. Additional functionality may also include defining a layer of simple workflow functionality for the fields of the form template that allows the form designer to formalize the sequence of activities in the business process, and to provide for conditional logic, also using the formula-based programming language where applicable.

The server based form engine (120) may receive a form template (150) from the form designer component (141) and provide the form template (150) for distribution to form filling client systems (161-163).

The form engine (120) allows business process participants to complete and submit the forms designed with the form designer component (141) using client software (for example, a web browser) at the form filling client systems (161-163).

The form filling client systems (161-163) may include a form filling component (180) including an interpreter component (181) for interpreting a form template (150) and providing a form instance (170) for input of data at the client system (161-163). The form template (150) that is created using the form designer may be stored in a proprietary file format that may be used by the form filling client systems (161-163) directly without conversion.

The interpreter component (181) may include functionality as explained further below for interpreting the cell-oriented spreadsheet formulae of the form template (150) as well as the additional functionality defined in the form template (150) including metadata specifying a required format of a cell input in a field, validation rules for the input fields, and defining workflow functionality for the fields.

The interpreter component (181) may faithfully reproduce the two-dimensional layout specified in form template (150) for each instance of the form. The interpreter component (181) may evaluate formulae to update calculated values, check the form validation rules, and enforce the workflow rules that were specified in the spreadsheet format template.

The form engine (120) may receive and record the data from each form instance (170) from form filling clients in a centralized database (130). The form engine (120) may therefore deal with multiple records of data generated for the same form template (150) and may provide ways to query and interact with those data sets.

In an alternative embodiment, the form engine (120) at the server (110) may implement the interpretation of a form template (150) for forwarding to a form filling client system (161-163) as a form instance (170); however, providing the interpretation functionality at the client makes it more responsive to the user.

In one embodiment, the designer system (140) may be provided at a client system which also includes the functionality of the form filling component (180) such that a user of the client system may act in both a form designer capacity and a form filling capacity.

This technology provides an intuitive way to combine two well-known paradigms (spreadsheets and BPM systems) in a way that adds a high level of functionality while retaining more familiarity and ease of use for untrained users than traditional workflow design systems.

Referring to FIG. 2, a flow diagram (200) shows an example embodiment of the described method as carried out at the form designer component (141). The form designer component (141) may be an application interacted with by a user. The method may provide (201) a user interface for creating a spreadsheet format form template (150) for a form.

The method may create (202) the form template which may include selecting cells within the spreadsheet which are defined for inputs into fields of the form instance. Usual spreadsheet manipulations and editing may be used, for example to specify titles, merge cells, define the overall size, etc. Copy-and-paste from a spreadsheet application may be used.

Creating the form template may include defining (203) cells with formula-based values which may be dependent on other cell inputs and/or may import inputs from another source. Creating the form template may also include defining (204) cells with metadata specifying the required format or type input required in a field. Creating the form template may also include defining (205, 206) validation rules and workflow functions. Although these functions are shown in a sequence in the flow diagram, during the usual design process these may be defined in any order and may be inter-related.

Once completed, the form template may be sent (207) to the form engine (120) for distribution to form filling clients (161-163) for interpretation as form instances (170) and input data capture.

The form engine (120) may receive a form template (150) from a form designer component (141). The form template (150) may be provided to form filling clients for interpretation as form instances (170) and input of data. Input data may be received at the form engine (120) and compiled in a database (130). In an alternative embodiment, the form engine (120) may interpret the form template (150) and provide the form instances (170) to the form filling clients.

The form engine (120) may provide the form template (150) to the form filling client systems (161-163) essentially unaltered and the formula-based values, data input controls, validation rules and workflow are all displayed in a user interface through which a user may interact with the form data there.

Referring to FIG. 3, a flow diagram (300) shows an example embodiment of the described method as carried out at a form filling client system (161).

A form filling component (180) at a form filling client system (161) may receive (301) or download a form template (150) from the form engine (120). In one embodiment, the form filling component (180) may be an application, such as a JavaScript application, that executes in a browser at the client system (161).

The form filling component (180) may render (302) a form instance (170) from the form template (150) including providing displayable input controls for fields of the form instance (170) based on the metadata in the cells of the form template (150) defining field input format or type. In one embodiment, the form filling component (180) may use hypertext markup language (HTML) templating to render the form instance (170) as an HTML page with appropriate input controls. In another embodiment, the form filling component (180) may use a native mobile application graphical user interface on a mobile smartphone operating system.

The user may enter data into the input fields of the form instance (170) and form filling component (180) may receive (303) the input data. The form filling component (180) may evaluate (304) any spreadsheet formulae and may use the results for the following steps. The results may be used to update (305) dependent formula-based values for cells in the form instance (170) and other form instance content that displays these cells. The results may also be used to check (306) validity constraints based on validation rules provided in the form template. The results may also apply (307) workflow functions that are defined in the form template, including enabling/disabling, hiding/showing parts of the form content in the form instance.

The input data of the form instance (170) may be provided to the form engine (120). The input data may be provided to the form engine (120) as it is entered and when any change is made to the form instance by the user. In one embodiment, the values for formula-based cells may be sent to the form engine (120) along with the user entered values which saves the form engine (120) from having to re-evaluate the expressions. A completed form instance may be exported with user input data to a format such as a portable document format (PDF).

Referring to FIGS. 4A to 4D, screenshots (410, 420, 430, 440) are shown of an example implementation of a form designer component (141) which are used to illustrate features of the form designer component (141).

FIG. 4A illustrates that the form designer component (141) uses the two-dimensional layout principles of a spreadsheet, allowing a business process owner, or someone that they are supervising, to quickly put a form template (150) together based on spreadsheet formatting that makes efficient use of space. Cells may be merged (411) to allow for input or display fields of different sizes.

Each cell has metadata (412) that can be configured through an input control of the form designer component (141). In this example, a drop down menu of properties (413) is provided through which types, values and formats of a cell may be defined. This specifies, for example, which cells contain labels (414), which contain user entered data, and which contain calculated values. For user entered data, the form designer can specify what type of data is required to be entered for that cell.

FIG. 4B illustrates that cells may be populated with calculated values based on the cell-oriented programming paradigm, in the spreadsheet formula language familiar to users. The screenshot (420) shows a menu (421) of formulae which may be selected and cells (422) which may be populated with calculated values based on the formulae. This language supports expressions including the following: unary (−, %) and binary mathematical operators (+, −, *, /, ̂); Boolean operators (=, < >, <, <=, >, >=); a text concatenation operator (δ); parentheses allowing for modifications to normal order of operations (precedence rules); and predefined function calls. A library of commonly used spreadsheet functions may also be provided.

FIG. 4C illustrates that the form designer component (141) allows for the configuration of form data validation rules by providing a validation input control (431). As with the calculated values, the formula-based programming language may be used for these rules if applicable. This allows for rich form validation without requiring specialized computer programming. The forms engine may provide built-in validation that entered data is of the correct type, based on the cell metadata configured. However, it is often important to specify additional validation with a form design based on specific content of that form.

In this example, the validation rule is that when a user enters a value in cell B2 (432), it is marked as invalid if the calculated value in cell D2 (433) is greater than 40,000. The value of cell D2 (433) is dependent on the user entered value in B2 (432).

FIG. 4D illustrates workflow functions may be provided. In order to systematically formalise a business process, it is helpful to specify the sequence of activities in the business process as part of the form design. There are also many business processes that have conditional logic (for example, only requiring the user to complete a section of the form if they provide a particular answer to a question in an earlier part of the form).

In order to enable this workflow design, the form designer component (141) allows a form to be split into sections (441), and provides additional configuration points (442) for each section. The form designer can control when a section becomes enabled (i.e. can be edited), and when it is visible. The formula-based programming language can be used to specify these conditions if applicable.

In addition, there are configuration points for required approvals (443) for a section. If these are configured, after the user has submitted a completed form, the appropriate reviewers will need to review and approve the content, or send it back for revision. The forms engine provides built-in support for this workflow.

The forms engine (120) is a server-based application that allows business process participants to complete and submit the forms designed with the form designer component (141) using client software (for example, a web browser) at a form filing client (161).

Referring to FIGS. 5A to 5D, screenshots (510, 520, 530, 540) are shown of an example implementation of a form instance (170) provided at a form filling client (161).

FIG. 5A illustrates how the form instance (170) rendered in the form filing client (161) shown in the screenshot (510) faithfully reproduces the two-dimensional layout specified in the form template (150) being designed in FIG. 4A. Each instance of the form template displays the appropriate input controls (511, 512) based on the data type configured for each input. For example, where input type <Rich Text> was specified, text editing controls (511) are provided and where input type <Date & Time> was specified, calendar and clock controls (512) are provided.

Once the form instances (170) are provided to users, as the user updates input fields in the form, the form filling component (180) at the form filling client (161) evaluates any configured formulae to update calculated values. It also checks form validation rules. This is illustrated in FIG. 58 which shows an input field (521) and a calculated field (522) corresponding to the cells (432, 433) in FIG. 4C. An invalid prompt is provided (523) based on the custom form validation (524).

FIG. 5C illustrates that the form filling component (180) also enforces configured workflow rules, including the built-in workflow for approvals. In this case, the entry is a “Near Miss”, not an “Incident”, so the conditionally visible second section about injuries is not shown (as provided in FIG. 4D). Built in submission, approval, revision implementation (532) is shown.

The forms engine (120) receives and stores the data from each form instance record in a centralised database (130). FIG. 5D illustrates the captured input data in a database (130). This means that it can therefore deal with multiple records of data generated for the same form template, and provide ways to query and interact with those data set, for example, providing summarized information relating to instances of the form.

The described technology brings the familiarity and end-user programmability of a spreadsheet into an enterprise BPM solution and has the potential to enable rapid digitisation of business processes in an enterprise way, without needing the services of trained technicians or professional computer programmers.

Referring to FIG. 6, a designer system (140) is shown which may be a client computer for example in the form of a desktop computer, laptop computer, tablet or smartphone. The designer system (140) may include at least one processor (601), a hardware module, or a circuit for executing the functions of the described components.

In the form template, a plurality of the cells define formula-based values, and a plurality of the cells include metadata specifying a required format of the cell input.

The form engine (120) makes the form template available to form filling client systems (161), for example, for download for interpreting locally at the form filling client system (161). In an alternative embodiment, the form template may be available to view and interact with via the form engine (120).

The form engine (120) includes a data receiving component (712) for receiving input data for form instances from form filling client systems (161). The form engine (120) may include a data compiling component (713) for compiling the input data in a database (130).
